Convert 45°C to °F: This guide will explain the relationship between Celsius (°C) and Fahrenheit (°F), the formula used for conversion, and how to apply it to convert 45°C to °F. Understanding these conversions is essential for interpreting temperatures in different parts of the world, as Celsius is commonly used in most countries while Fahrenheit is used in the United States.

Relationship Between Celsius and Fahrenheit
The Celsius and Fahrenheit scales are two different systems for measuring temperature. The key points where they align are at -40°, where both scales intersect, and at the freezing and boiling points of water.
On the Celsius scale, water freezes at 0°C and boils at 100°C. On the Fahrenheit scale, water freezes at 32°F and boils at 212°F. The difference between the boiling and freezing points is 100 degrees on the Celsius scale but 180 degrees on the Fahrenheit scale.
The Formula for Conversion
To convert Celsius to Fahrenheit, you can use the formula:
°F = (°C × 9/5) + 32
This formula is derived from the relationship between the two scales. The factor of 9/5 accounts for the different intervals on the two scales (180°F for 100°C), and adding 32 aligns the starting points of the scales (0°C equals 32°F).
How to Convert 45°C to Fahrenheit
Now, let’s apply the conversion formula to convert 45°C to °F step by step.
Step 1: Use the Formula
The formula for conversion is:
°F = (°C × 9/5) + 32
Step 2: Plug in 45 for °C
Substitute 45 for °C in the formula:
°F = (45 × 9/5) + 32
Step 3: Perform the Multiplication and Addition
First, calculate 45 × 9/5, which equals 81.
°F = 81 + 32
Next, add 32 to 81 to get 113.
°F = 113
Answer: Therefore, 45°C is equal to 113°F.
